Kinda pricey for what included.
Top reviews from the United States
There was a problem filtering reviews. Please reload the page.
- Reviewed in the United States on May 6, 2025This is a case for those who really care about size. It is designed for use with an ITX motherboard.
And extra slim line fans. Let me start with the pros, all of the cabling for the case is included in the terms of u. USB ports,
Power button and front speaker microphone connection. Everything fit together well like it was supposed too, and after being fully built , the case does run silent. This case allows for 3 fans, ether 120mm or 140mm however you need the slimline 15mm fans as any bigger will not fit. A big minu is that the fans are not included which make this case pricey to have to buy them. Also the slimline fans are harder to find. Fans vent do not have filters so dust management will be necessary. A plus is that video card flex cable was included. With a case this small the video card sit opposite of the motherboard. Be sure to get a motherboard with a SSD slot as there or no HDD racks. All in all it is a decent ITX build just know everything needed before you start. Also instructions are very poor.

- Reviewed in the United States on May 10, 2025This case seriously impressed me—it’s super compact but still fits a full-size GPU and ATX power supply without feeling cramped. The airflow is great with all the mesh panels, and it even comes with a PCIe 4.0 riser and DisplayPort extension so setup was super smooth. Perfect for a clean, powerful build that doesn't hog desk space.
- Reviewed in the United States on April 30, 2025I thought this was bad, but I already have to edit my review after finishing my build. Just to get all the cons out of the way: there are no HDD mounts at all, no way to squeeze a real fan in two of the three positions... this requires custom sized 15mm fans which are not included, no cable paths and all the obvious cable routing spots are in front of fans. My original review is below.
This chassis is a good option for those who need a large ITX case. This case can support for an ATX PSU and full length, full height, triple wide PCIe cards, and 140mm fans. The value seems off considering the all mesh construction and, despite the listing indicating their inclusion, no fans are included. Honestly, I would expect a PSU and fans at this price point. If you already have a box of fans, note this case only supports 15mm slim fans. The PCIe configuration could also be a deal breaker for many builds, especially content creators.
The three space full height full length PCI cage provides more than adequate room for just about any video card. Unfortunately, the orientation of the PCIe cage faces downwards, which will almost certainly cause cabling issues. An older spec 90 degree DP (1.4 / 4k) cable is included for this purpose, but it is important to note that for any card in your system, the external cabling will only have about 3/4 of an inch of clearance before the whole weight of the pc will be straining your cable and card port. If your card uses DVI or a breakout cable, this case just won't work for you. Any other cabling exiting your PCIe card- HDMI, audio, modern DP, et cetera will all likely need to be 90 degree cables to avoid straining cables and ports.
While designed for gaming, this would *almost* make for a great server chassis, if it weren't for some strange design choices. This chassis' large PCIe cage area could fit multiple PCIe cards for ITX boards that support bifurcation (or an m.2 slot could be passed to PCIe). There's plenty of room, for example, to house a full length fiber nic and a Tesla AI accelerator if you're building an IP Cam server if you have the capability to connect these. However besides simply fitting, many server cards won't be properly cooled with the case's all mesh design, the previously mentioned exit path for cabling, and that the advertised 2 X 2.5 drive mount is not included. Yeah... There is no way to mount a hard drive in this case without buying more parts.
This is marketed as a gaming/content creator/professional case, so no knocks for being a less than ideal design for a server. This is still extremely bare bones and represents a poor value. There's no lighting or ARGB headers, no fans (despite requiring an odd size and advertised as included), Extremely limited front panel access for pro users (2XUSB A, 1 USB C), outdated riser (either PCIe 3 or 4, depending on which case you buy; necessary based on case shape), no room for PCIe cabling necessary for serious content creation or gaming, outdated DP cable (necessary for the odd PCIe setup), cheap aesthetic, no cable management system (besides a couple zip ties), no cable paths outside of fan locations, no alternative PSU brackets, and a whopping total of zero HDD mounts. I will build a great system out of this case, and there's plenty of space to do so, but I'll need to add a whole lot of parts and time to get it to that level. That being said, better cases can be had for a quarter this price.
- Reviewed in the United States on May 2, 2025This is a little misleading, as I thought especially for the price, the RGB fans were included. But that's my fault for not reading the fine print. Price is quite high for a small case. Larger cases with a lot more features and RGB fans included are less.
Otherwise, I'm super excited about this case. Super small, lightweight, looks great. Just price is much higher than it should be.
- Reviewed in the United States on May 8, 2025They are making more and more of these ITX cases as people's desktops are taking up less area than in the past. This case offers a small footprint to accomplish that. In the specialized areas, you can get a 3-fan GPU and a 360mm cooler vertically. It can also accommodate three 140mm fans to either blow in or exhaust the air. A couple of the manufacturers make high-end boards in the ITX size, which also include Thunderbolt, and the new Intel 1815 CPU. If you want the powerful Intel Ultra 9 Processor, I would be sure to use high-speed, high-pressure fans to move the air through the radiator and out of the case. With these small ITX cases, the interiors get packed with components and don't have a lot of free-air space to circulate. You'll end up with a powerful desktop that takes up very little space on your desk.
